sin(x) 2 ------ + cos (x) 1
sin(x)/1 + cos(x)^2
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
The derivative of sine is cosine:
So, the result is:
Let .
Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
The derivative of cosine is negative sine:
The result of the chain rule is:
The result is:
Now simplify:
The answer is:
-2*cos(x)*sin(x) + cos(x)
2 2 -sin(x) - 2*cos (x) + 2*sin (x)
